I'd think most of it is trauma, he's overly passive, because that's the mindset he was encouraged into by his brother. In his brain if he is too active, then his brother will kill him. By extension, this mindset is represented to others too, ESPECIALLY a love interest.
Another thing, he's just desperate for someone on his side and the ml is pretty much the only option here. If he tries to get help from grandpa (another person on his side), his brother will try to kill him
Honestly, I’ve been wondering if there’s a psychological term that could explain Yigon’s behavior. Some readers pointed out how overly passive he is despite being terrified of his brother, and I kind of agree. It’s strange how he’s not even aware (or maybe just pretending not to be) that everyone around him like his bodyguard or his secretary is working under his brother’s orders. Or maybe he is aware, but just completely powerless to act on it.
I don’t think Yigon is stupid or helpless. In fact, he probably could gather evidence and fight back. But what if the issue isn’t about ability, but about mental state? From what we’ve seen, he might be experiencing something close to learned helplessness or even complex trauma. He’s been controlled and manipulated for so long that his brain just… gave up on the idea of real freedom. When you live in fear every day, you stop thinking about long-term escape and start focusing only on how to survive today.
That’s why I don’t think it’s unreasonable that Yigon turns to someone like Taekang. Everyone else in his life is already “broken” and compromised. He doesn’t have anyone trustworthy left. So even if he knows what needs to be done, he’s too afraid and too alone to do it himself. Taekang, despite being reckless and blunt, becomes the closest thing to a lifeline.
I thought I’d take a break from this story for a while… but honestly, things like this are just too compelling for me to walk away from. Guess I’m here to stay and see :)
